[Q] how to mount cdrom as rw?

how can I mount the /dev/block/mmcblk1p17 as read write.
I have tried:
[email protected]:/# mount -t iso9660 /dev/block/mmcblk1p17 /data/local/mystuff/cdrom2
and
[email protected]:/# mount -o remount,rw /dev/block/mmcblk1p17 /data/local/mystuff/cdrom2
Always shows as read only though:
[email protected]:/# mount |grep cdrom
mount |grep cdrom
/dev/block/mmcblk1p17 /data/local/mystuff/cdrom2 iso9660 ro,relatime 0 0
I would like to update the motohelper driver file to latest version on this partition. Any ideas on how to do this?

Recover data from galaxy s plus with broken screen

Hello, I have a samsung galxy s plus with cm11 and a broken screen and i want to recover data from internal storage
when the phone is on i cannot access adb
in recovery i can use adb shell but don't know how to mount the internal storage.
I've tried several ways to mount but didn't work
here is my fstab
Code:
/dev/block/mmcblk0p16 /cache ext4 rw
/dev/block/mmcblk0p17 /data ext4 rw
/dev/block/mmcblk0p15 /system ext4 rw
and recovery.fstab
Code:
# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
/dev/block/mmcblk0p8 /boot emmc defaults recoveryonly
/dev/block/mmcblk0p13 /recovery emmc defaults recoveryonly
/dev/block/mmcblk0p15 /system ext4 ro,errors=panic wait
/dev/block/mmcblk0p16 /cache ext4 nosuid,nodev,barrier=1 wait,check
/dev/block/mmcblk0p17 /data ext4 nosuid,nodev,noatime,noauto_da_alloc,journal_async_commit,errors=panic wait,check,encryptable=footer,length=-16384
/devices/platform/msm_sdcc.2/mmc_host/mmc1 /storage/sdcard0 vfat defaults voldmanaged=sdcard0:28,nonremovable
/devices/platform/msm_sdcc.4/mmc_host/mmc2 /storage/sdcard1 vfat defaults voldmanaged=sdcard1:auto
/devices/platform/msm_hsusb_host.0 /storage/usbdisk auto defaults voldmanaged=usbdisk:auto
can anyone help?
Google Android commander. Turn your phone on and use that to get all your files.

the problem is i've modified build.prop to try to enable MTP instead of UMS but now i have boot loop (it vibrates) and even after pushing the backup of build.prop on the phone, the phone still doesn't boot. I can only use the recovery.
anyone?, Im sure there is a way but I just can't find one

[HELP] broken lcd + after working with adb doesnt boot

Hey xda-community,
might be a long text to read but i want to make it as detailed as possible :/.
I have an i9070 with broken lsd (+touch not working) and pattern lock.
i booted into recoverymode (TWRP) and removed the pattern lock via adb shell ("rm /data/system/gesture.key").
i wanted to use [email protected] so i tried to activate USB Debugging via adb shell.
in the internet i found a method and tried it right away
i had to pull /system/build.prop
add the line "persist.service.adb.enable=1" in the file
and after that i had to push it back, but i couln't.
So i searched to mount /system r/w ..... (prob for the false device ,_, )
i tried the 1st command and forgot the 4 in ext4, so i typed it like this in the adb shell:
# mount -o rw,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o rw,remount -t ext4 /dev/block/mmcblk0p8 /system
after that i was able to push the build.prob back, and used
# mount -o ro,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o ro,remount -t ext4 /dev/block/mmcblk0p8 /system
afterwards.
Rebooted it and it stuck while booting prob.
So i tried the push back the original build.prop. (thought it might be the cause)
Still not booting..
I ended trying all commands without any order:
# mount -o ro,remount -t ext /dev/block/mmcblk0p3 /system
# mount -o rw,remount -t ext /dev/block/mmcblk0p3 /system
# mount -o ro,remount -t ext4 /dev/block/mmcblk0p3 /system
# mount -o rw,remount -t ext4 /dev/block/mmcblk0p3 /system
# mount -o ro,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o rw,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o ro,remount -t ext4 /dev/block/mmcblk0p8 /system
# mount -o rw,remount -t ext4 /dev/block/mmcblk0p8 /system
chmod 755 system
chmod 777 system
i used also mount..../mmcblk0p3 instead of mmcblk0p8 because after using "mount" it showed behind the /system mmcblk0p3 ...
i messed too much around as a newbie :crying:
I am still able to use adb in recovery mode but cant acces the internal storage.
Would be nice if someone could help me
Ty if you read the whole text .. ^^

this method would solve the changed partition problem xt 1078 by the xt1068 partition.

You read that right ?, while installing THEME, is appended to the menu "mount" The "persist" partition friend. please follow the instruction
Work Only in the version ** TWRP 3.0.0-1 **, and Version 1 from the theme or 2, I am no sure in this moment. [emoji16]
